Dense rainforests were long thought to be some of the last places where early humans could survive. For decades, researchers believed that our ancestors stuck primarily to open grasslands and coastal areas, avoiding the dense forests of Africa until much later in history. Evidence from West Africa is now forcing scientists to dramatically reconsider that assumption. Researchers investigating ruins in what is now Ivory Coast have found evidence that humans lived in humid tropical forests around 150,000 years ago. The discovery pushes back the oldest known evidence of rainforest habitation by more than double previous estimates and suggests that early…

New research from Edith Cowan University (ECU) could provide an important boost to efforts to save the world’s rarest marsupials. The Gilbert Potoroo is an endangered species found only in Western Australia, with fewer than 150 animals left in the wild. Scientists from ECU and the Department of Biodiversity, Conservation and Attractions (DBCA) are working together to better understand what the small marsupials eat, so conservation teams can identify suitable new habitats and secure the future of the species. “We aim to recover species through translocation, where we move organisms from one place to another, creating an insurance population in…

A new study from the University of Waterloo uses mathematical modeling to examine how vitamin C affects chemical reactions in the digestive system that are associated with the development of cancer. Over the past few decades, exposure to nitrates and nitrites has steadily increased in North American diets. Nitrates and nitrites are compounds found in cured meats and fruits and vegetables grown using contaminated soil or water. Nitrates and nitrites play important roles in nerve and heart health, but in the stomach they can undergo a chemical reaction known as nitrosation, forming chemicals that many scientists suspect increase cancer risk.…

Bedfont® Scientific Ltd., an innovative leader in the medical breath analysis industry with almost 50 years of experience, is pleased to be joining thousands of medical professionals at this year’s European Academy of Allergy and Clinical Immunology (EAACI) Congress 2026 on stand I03 to introduce its NObreath® and Gastrolyzer® series of non-invasive breath analyzers.

The conference, which will be held from Friday 12th to Sunday 14th June in Turkiye, Istanbul, is widely recognized as the world’s largest and most influential conference dedicated to allergy and clinical immunology. Each year, thousands of clinicians, researchers, and health…

DZNE researchers have generated new insights into how the human genome shapes the chemical composition and concentration of blood lipids. They identified more than 50 regions across the genome with no previously known association with lipid metabolism. The findings, based on blood samples from more than 8,000 people, have the potential to improve our understanding of the aging process and pathological conditions such as Alzheimer’s disease, diabetes and cardiovascular dysfunction. The results were published in a scientific journal nature communications. These are based on the sample and additional research data from the Rhineland Study, a population-based study conducted in Bonn,…

Scientists have recorded the incredible feat of whale migration for the first time, confirming that humpback whales traveled more than 14,000 kilometers of open ocean between eastern Australia and their breeding grounds in Brazil. This discovery marks the largest distance ever recorded between individual sightings of humpback whales around the world. “Discoveries like this are only possible thanks to decades of investment in long-term research programs and international collaboration,” said co-author Stephanie Stack, a PhD candidate at Griffith University. “Even though these whales were photographed by different people, decades apart and in opposite parts of the world across two different…

Most people living with severe asthma also struggle with other, less obvious health conditions, a major new study has found. Analyzing data from thousands of patients, researchers found that additional diseases, ranging from obesity to osteoporosis, tend to appear in clusters. They say identifying these patterns could be the key to unlocking more effective treatments for those hardest hit by the condition. The research, published in The Lancet Regional Health, was led by academics from the University of Southampton, Southampton University Hospital and the National Institute for Health Research (NIHR) Southampton Biomedical Research Center (BRC). The experts were collaborating with…

Handwriting is a cognitively challenging task because it requires a combination of fine motor control and complex mental skills such as selecting, organizing, and interpreting sensory information. Because of the high demand on the brain, it is a potential marker of cognitive decline, especially with age. This often results in slow or choppy handwriting. Now new Frontiers of human neuroscience In this study, a team of Portuguese researchers investigated whether handwriting characteristics, such as speed and stroke composition, differ between older adults who show signs of cognitive decline and those who do not, and whether handwriting characteristics could therefore serve…

A new study reveals partially distinct frequency-specific electroencephalogram (EEG) oscillatory patterns in response to food and alcohol cues, reflecting different motivational processes in the brain. Research: Brain signatures of food and alcohol stimulus processing: A comparative EEG study. Image credit: Master1305 / Shutterstock recent Frontiers of human neuroscience In this study, we investigated whether sustained EEG oscillatory dynamics differentiate neural processing of food and alcohol cues. Processing food and alcohol cues Motivated behavior is defined as behavior that promotes survival by directing an organism toward biologically relevant goals. These behaviors require interaction with the environment and demonstrate neural connections between…

Women with low vitamin D levels may have a more painful recovery after breast cancer surgery and may require significantly more opioid drugs afterwards, according to research published in the online journal Local anesthesia and pain treatment. The results of this study suggest that breast cancer patients with vitamin D deficiency (
